Ride into the network
like you own it.

SubnetSlinger is the modern network engineer's toolkit — ping, trace, packet capture, DNS, SNMP, discovery, and an AI Deputy and Posse. The toolkit runs fully local — no telemetry, and the free tier needs no account. The AI is optional and off by default: run it locally with Ollama, or bring your own cloud key (Anthropic, OpenAI, or Gemini). No upsell ads in your face.

A modern replacement for the aging enterprise toolkits network engineers have outgrown — buy once, no subscription, every tool included, every desktop OS, no server host.

The frontier problem

The gear got smarter. The tools got scattered.

The old way

A licensed desktop toolset — one per seat, pricey and dated. But it lived on your own machine and was always there the moment you needed it.

The new way

Powerful centralized platforms and automation. But they live on a server. Can't reach it — or the admin who runs it is busy — and you're stuck without the tool or the help.

The gap

The engineer provisioning new gear, troubleshooting in the field, or building out a lab who needs the tool right now — on the machine in front of them, not behind a server or a support ticket.

SubnetSlinger bridges the gap.

Built by a network engineer who kept hitting that wall. Every tool a working engineer actually reaches for, carried with you on your own machine — no server to reach, no admin to wait on. New protocols get added as the wire changes; and legacy needs stay covered — when you still need to watch raw packets, the built-in Capture tool does exactly that: filter down to just the traffic you care about, and export straight to Wireshark.

Your network data never leaves your machine.

AI is opt-in: run it locally with Ollama and nothing leaves, or use your own cloud key — your choice, depending on the model you pick.

The six-shooter, and then some

46 tools. One toolkit.

Organized the way an engineer thinks — reachability, names, discovery, access, records. And a game.

46 tools on the desktop + the Subnet Slinger arcade game. Counts vary by platform — see below. New protocols added as the wire changes.

Ride any horse

Desktop. Laptop. Phone in your pocket.

For the moments you can't reach your usual network or server-side tools — provisioning new gear, troubleshooting in the field, or building out a lab. It's the tool you need, on whatever device you've got. Buy the desktop once and it's yours on Windows, macOS, and Linux — every update included, no subscription. The iPhone, iPad, and Android apps are free companions, free for everyone.

Tool counts vary by platform — macOS carries the most, and every version includes tools built specifically for that OS (native Wi-Fi scanning, OS connection tables, platform packet capture). The desktop apps carry the full toolkit; the free iPhone, iPad, and Android companions carry a focused 30+.

iPad — a free companion, and a field tool in its own right

The iPad app is free for everyone, shipped as its own platform version — not a stretched-out phone build. A cellular iPad makes an ideal field-testing rig: a big screen to actually read a capture or a topology map, with its own LTE/5G path for out-of-band checks — so you can probe and diagnose from the edge of the network without tying up your phone.
